IMPORTNT NOTE:
The AUX 1 INPUT jacks and the Bluetooth input are wired in parallel. If both the AUX 1 INPUT
and the Bluetooth input are broadcasting at the same time both sources will be heard
simultaneously. When using the AUX 1 INPUT always turn your Bluetooth device OFF. When
using your Bluetooth device always turn your AUX 1 INPUT source off.
AUX 1 OUTPUT (RCA):
8
The AUX 1 OUTPUT is a line level variable pre-amp output which can be used to connect the line
level output of the MA202R to other devices such as auxiliary amplifiers, mixers or more commonly
powered subwoofers like the Carver BAS8. This is the most common connection for the AUX 1
OUTPUT. This output is variable which means when the front panel master volume control is
adjusted up/down the level of the AUX 1 OUTPUT will also change or “track”. This is very useful
when connecting the MA202R to a powered subwoofer which will have its own volume control.
Once the desired subwoofer volume is achieved the MA202R will raise or lower the subwoofer
volume in conjunction with the main speakers connected to the MA202R speaker outputs.
SPEAKER OUTPUT TERMINALS:
9
The speaker output terminals are 5 way binding posts that will accept speaker wire gauges from
18awg to 12awg with direct wire-in, spade lug or banana jack connections. Turn the terminal
counter clockwise to unscrew the protector and expose the terminal for direct wire-in. Turn the
terminal clockwise to tighten the protector over the wire and never over tighten. Connect your
(min 4ohm) left channel speaker to the “L” terminal keeping the + positive wire to the RED
connector and the – negative wire to the BLACK terminal. Repeat these connections for your
(min 4ohm) right channel speaker. Pay close attention to the polarity of the wires. Always keep
the + to RED and the – to BLACK. Crossing any one of these connections can create reverse polarity
in one speaker which will destroy the sound quality of your stereo system.
IMPORTANT NOTE: Never cross positive and negative wires. This will short the amplifier
potentially causing damage to the MA202R.
SPEAKER OUTPUT TERMINALS BRIDGE MONO:
10
In bridge mono mode connect one (min 8ohm) speaker to the following terminals, + positive
to the LEFT RED terminal and the – negative to the RIGHT BLACK terminal. Leave the other two
terminals unconnected.
AC POWER INLET:
11
Connect the supplied AC power cable to the AC inlet jack and push into place making sure that
the AC cable is fully inserted. If the MA202R will be left unused for an extended period of time
we recommend that the power cord be disconnected from the wall outlet. This will insure that
power surges, power brownouts and lightning strikes will not damage the MA202R.
BACK PANEL FAN PORT:
12
The MA202R back panel fan port should never be blocked. Always provide a minimum of 3 inches
of clearance from the back of the unit to any wall or solid surface. We recommend that you
vacuum the vent periodically to remove dust and contaminates that can clog the fan and the
fan port.
